When this script is run in a XUL page: Function.prototype.foo = function() { alert("foo"); }; var f = function() { }; f.foo(); ...the last statement will raise the error "f.foo is not a function". Note that: var f = new Function(); f.foo(); ..does work. Also note that all of this works fine in a web page as well as in xpcshell. Reproducible: Always

Gah, I meant to say that is similar to bug 343966, not bug 344052.

I'll update the summary of bug 300079 to make it more obviously the dup target. /be *** This bug has been marked as a duplicate of 300079 ***
